Adafruit_SleepyDog on M0 feather radio.sleep

Post by jimk123 »

I bought two of these radio boards https://www.adafruit.com/product/3176 and in the tutorial it says

// To put the chip into ultra-low-power mode replace delay with these lines:
// NOTE !!! the USB will disconnect so do this after you have done all your debugging!

rf69.sleep();
Watchdog.sleep(60000); //https://github.com/adafruit/Adafruit_SleepyDog
// delay(60000);

BUT I noticed it only sleeps about 15 seconds. In the github link I read somewhere the actual max sleep time depends on the board. Can someone recommend a way to sleep for a minute ? My goal is to have the TX board outside running on a lipo battery sending a temp reading once a minute and I am trying to use as a little power as possible.
thanks

There are two deep sleep examples using the LowPowerLab library:
